A humid subtropical climate is a subtype of the continental climate because it also exhibit similar temperature ranges. It is a zone of climate characterized by hot, humid and wet summers.
Answer: 6 electrons
Explanation: Oxygen atom has atomic no of 8 which means it has got 8 electrons. n=2 depicts that the electrons have principle quantum no = 2. According to Afbau's rule the electrons are arranged in shells of increasing energy as follows:
Thus there are 2 electrons in 2s and 4 electrons in 2p which makes a total of 6 electrons.
thunderstorm.
c.
hurricane.
b.
tornado.
d.
flash flood.
The correct answer is Flash flood.
A sudden flood that is a result of heavy rain is called a flash flood. It lies in the low lying areas. The rain might sometimes accompany thunderstorm, hurricane, or snowfield. The difference between a flash flood and normal flood is that it lasts less than till 6 hours. In this case a high place can be used as a temporary shelter and once the flash flood is gone, anyone can shift to his or her normal routine.
It is easier and more effective to prevent pollution than to clean up and dispose of waste.
b.
Remediation of contamination is easier than pollution prevention.
c.
Habitat restoration cannot be undertaken with modern technologies.
d.
Safe waste disposal is the easiest was to minimize environmental risk.
The control of pollution is key to minimize environmentalrisk due it is easier and more effective to prevent pollution than to clean up and dispose of waste (option A).
Pollution refers to the contamination of water, air (atmosphere), and soils with nocive substances that may be harmful to the environment.
In conclusion, it is easier and more effective to prevent pollution than to clean up and dispose of waste (option A).

The correct answer for this question is a) It is easier and more effective to prevent pollution than to clean up and dispose of waste.
Yes, it is more effective way to control environmental risk by preventing pollution at its source. First it help us to control the flow of toxicity through water and air. It is often more difficult and expensive to control pollution after it has been released into the environment so it will also help us to cut the cost of treatment of pollutants
